My '91 exhibited "Vanagon Syndrome" only in cold weather.  Typically
after about an hour at speed on a 300 mile trip during the winter
holiday season.  I believe that the first record of this being a
recognized problem was by a Scandinavian tech who also encountered it in
cold weather and got VW to take note.  This may be in a file on
Vanagon.com somewhere.
   Everyone should do the "capacitor fix".
